Living World Season 4 refers to a schedule of future content updates, beginning on the 28th of November, 2017. It will continue the story of Guild Wars 2: Path of Fire, picking up immediately where the story instance Small Victory (Epilogue) left off.

A new Keys category has been added to the wallet, and it contains a currency version of several existing items. These items can be consumed to convert them into the new currencies. Content that once required these items to be in a player's inventory will now check for the currency instead. This change affects the following items:
Zephyrite Lockpicks
Bandit Skeleton Keys
Pact Crowbars
Exalted Keys
Vials of Chak Acid
Machetes
Trader's Keys
